INSTALLATION INSTRUCTIONS
2017 Edition
Please read these instructions carefully before installation, assembly or use
of any product and keep this manual on hand for future use and reference.

1. INSPECT PIPE ENDS: For optimum sealing
by the gasket, the exterior surface of the pipe
ends must be free from any indentations, pro-
jections, roll marks or other harmful surface
defects such as loose paint, scale, dirt, chips,
grease and rust.
2. CHECK GASKET: Verify the gasket supplied
is correct for the intended service. Color code
identifies gasket grade.
☞ Refer to page 36 for additional information
on gaskets.
3. LUBRICATE GASKET: To help insert pipe
smoothly and mount couplings smoothly with-
out pinching, apply a thin layer of Shurjoint Lu-
bricant to the sealing lips of the gasket and as
well as to the exterior of the gasket. Other com-
patible lubricants may be used so long as they
are not harmful to the gasket. System tempera-
ture should also be considered when selecting a
lubricant. See page 38 for details.
Note: Lube-E gasket: Normally no lubricant is required when using a
Lube-E gasket.
4. INSTALL GASKET: Install the gasket over one
end of the pipe so that the pipe end is exposed.
No part of the gasket should overhang this end
of the pipe.
5. BRING THE MATING PIPE TOGETHER:
Bring together and align the two pipe ends to
be joined. Slide the gasket over the ends and
center it between the grooves of the pipe to be
joined. No part of the gasket should protrude
into the groove of either pipe.

3. INSTALL COUPLING HALVES: For a “swing-
over” installation, place one of the coupling
halves around the bottom side of the gasket and
swing over the other coupling half into position
over the top side of the gasket. In tight areas
where a swing-over is not possible, install the
coupling halves one at a time. In both cases
make sure the coupling keys are engaged in the
grooves.
4. INSERT BOLT & NUT: Insert the remaining
bolt and apply the nut hand-tight. Make sure that
the oval neck of the bolt engages into the bolt
hole of the housing.
5. TIGHTEN NUTS (For 1¼” to 12” Models
Z07 and Z05 Couplings): Tighten nuts alter-
nately and equally until the bolt pads meet and
make metal-to-metal contact. Tighten nuts by
another one quarter to one half turn to make
sure the bolts and nuts are snug and secure. The
use of a torque wrench is not required.

2. ASSEMBLE COUPLING: For a “swing-over”
assembly loosely install one bolt and nut on one
side of the coupling. For a standard assembly
start with the two housings separated.

CAUTION
1. Uneven tightening of bolts and nuts may cause the gasket to be
pinched, resulting in an immediate or delayed leak.
2. Never exceed torque stated in the table on page 34. Excessive tight-
ening of nuts may cause a bolt or joint failure.
NOTE: As the coupling bolts are tightened,
the angled bolt pads slide in opposite
directions causing the coupling keys to
tightly grip the pipe, while at the same time
the pipe grooves are forced outward against
the coupling keys. The bolt pads should
always maintain metal-to-metal contact.
Tighten nuts by another one quarter to one
half turn to make sure the bolts and nuts
are snug and secure. The use of a torque
wrench is not required.

6. LARGE DIAMETER COUPLING: Large di-
ameter couplings over 14” consist of three to
four housing segments. To prepare installation,
preassemble the segments loosely into two
or three equal assemblies depending on sizes.
Install those assemblies over the gasket in the
same manner as described above.
7. TIGHTEN NUTS (For 14” to 24” Models Z07
& Z07N Couplings): Tighten nuts alternately
and equally until the bolt pads meet and make
metal-to-metal contact. Tighten nuts by another
one quarter to one half turn to make sure the
bolts and nuts are snug and secure. The use of a
torque wrench is not required.
